Abstract
The present invention provides a system, method, and computer-readable medium for quarantining a file. Embodiments of the present invention are included in antivirus software that maintains a user interface. From the user interface, a user may issue a command to quarantine a file or the quarantine process may be initiated automatically by the antivirus software after malware is identified. When a file is marked for quarantine, aspects of the present invention encode file data with a function that is reversible. Then a set of metadata is identified that describes attributes of the file including any heightened security features that are used to limit access to the file. The metadata is moved to a quarantine folder, while the encoded file remains at the same location in the file system. As a result, the encoded file maintains the same file attributes as the original, non-quarantined file, including any heightened security features.
